WILLIAM HARLEY BELL, OF HUNTSVILLE, ALABAMA.

MACHINE FOR WRAPPING GRAFTS.

Application filed February 5, 1908.

To all whom it may concern:

Be it known that I, l/VILLIAu H. BELL, a citizen of the United States, and a resident of Huntsville, in the county of Madison and State of Alabama, have invented a new and Improved Machine for WVrapping Grafts, of which the following is a full, clear, and exact description.

The invention relates to grafting, object is to provide a new and im roved machine for wra ping twine or the like around the stock 311C scion, with a view to quickly and securely fasten the scion in place on the stock.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement;Fig. 2 is an enlarged longitudinal sectional elevation of the same; Fig. 3 is a transverse section of the same on the line 3-3 of Fig. 1, and Fig. 4 is an enlarged sectional side elevation of the twine-cutting mechanism.

On a suitably constructed stand A is mounted a bearing B, in which is journaled a shaft C carrying a wheel D, provided on its face with lugs D for supporting centers E, carrying a twine holder or a spool F, from which unwinds the twine G, to pass forward into and through a twine wrapping tube H, provided at its rear end with a curved racket H secured to the face of the wheel D.

By the arrangement described, the twine holder F is centrally supported in front of the wheel D, and the twine wrapping tube H is arranged parallel to the axis of the wheel D,

and consequently when the wheel D is rotated, the twine wrapping tube H is carried bodily around in a circle.

The twine G passes out of the front end of the twine wrapping tube H and is wrapped by the latter around the joint 0' the stock I and scion I, to securely fasten the same together.

In order to prevent wabbling of the twine wrapping tube H and breaking of the twine G at a point between the wrapping tube H, the stock I and scion I, a counterbalancing tube H is provided and secured to the face Specification of Letters Patent.

,P, journaled on the twine G and pressing the Patented May 5, 1908;

Serial No. 414,355.

of the wheel D diametrically opposite the tube H; and both tubes H and H are preferably inclosed in a cylindrical tube or hood H secured to the wheel D and terminating a short distance from the terminals of the tube H and H The stock I and the scion I are supported on a manually operated support J, mounted and its to slide lengthwise in suitable bearings K ar ranged on-the stand A, the top or the support J bringing the joint of the stock I and scion I approximately in axial alinement with the wheel D.

In order to hold the stock I and the scion I in a slightly inclined position, as indicated in Fig. 1, the support is cut out at its rear portion, as indicated in Fig. l. A lug L is secured to one side of the support J, to hold the stock I and the scion I against transverse movement during the wrapping operation.

In order to cut the twine G after the wrapping operation is completed, a manually controlled cutter M is employed and mounted to slide longitudinally in the support J,the

edge into the path of the twine G, to cut thesame at a point between the tube H and the stock I and scion I, thus leaving the twine projecting beyond the'end of the tube H in convenient reach of the operator, for the next wrapping operation.

The wheel D may be rotated in any suit able manner by hand or by power, preferably, however, by foot power, as illustrated in Fig. 1. For the purpose mentioned a treadle N, connected with the floor is connected by its pitman O with a crank wheel the stand A, and the said wheel P is connected by a belt Q, with a pulley R secured on the shaft 0, so that when the treadle N is actuated the wheel P and the pulley R are rotated, to cause rotation of the wheel D.

By the operation described, the operator can conveniently place the jointed stock I and the scion I in position on the support J, and then by taking hold of the outer end of same in contact with the jointed stock and scion, and rotating the wheel D, the twine is quickly wrapped around the joint of the stock I and the scion I, to securely unite the same. After the desired amount of twine has been wrapped around the stock I and scion I, then the operator pushes the cutter M forward to cut the twine as above described.

large number of grafts can be readily wrapped in the manner described in a comparatively short time.

The machine is very simple and durable in construction, and not liable easily to get out of order.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A machine for wrapping grafts, comprising a support for the stock and. scion, a twine wrapping tube having bodily move ment around the stock and scion, and a twine spool from which the wrapping twine unwinds for passing to and through the said twine wrapping tube.

2. A machine for wrapping grafts, comprising a twine wrapping tube for the pasbe wrapped around the stock and the scion, a wheel mounted to turn and on which the twine wrapping tube is secured approximately parallel to the axis of the wheel, and a twine holder mounted on the face of the wheel for delivering the twine to the said twine wrapping tube.

3. A machine for wrapping grafts, comprising a slidable support for the stock and scion, a twine wrapping tube for the passage of the twine to be wrapped around. the stock and the sclon, a wheel mounted to turn and 011 which the twine wrapping tube is secured approximately parallel to the axis of the wheel, and a twine holder mounted on the face of the wheel for delivering the twine to the said twine wrapping tube.

4. A machine for wrapping grafts, comprising a wheel mounted to turn, a twine holding spool journal'ed on the face of the said wheel, a twine wrapping tube provided. at its inner end with a curved bracket attached to the face of the wheel a distance from thecenter thereof, to hold the said twine wrapping tube parallel to the axis of the said wheel, the twine passing from the said spool to the inner end. of the said twine l wrapping tube, and through the same out of I the forward'end of the tube, and a support l for the stock and scion arranged in a plane extending through the axis of the said wheel.

5. A machine for wrapping grafts, comprising a wheel mounted to turn, a twine holding spool journaled on the face of the twine wrapping tube parallel to the axis of the said wheel, the twine passing from the said spool to the inner end. of the said twine wrapping tube and through the same, out of the forward end of the tube, and a support for the stock and scion mounted to slide longitudinally in a plane extending through the axis of the said wheel.

6. A machine for wrapping grafts, comprising a slidable support for the stock and scion, a twine wrapping tube for the passage of the twine to be wrapped around the stock and the scion, a wheel mounted to turn and on which the twine wrapping tube is secured approximately parallel to the axis of the wheel, a twine holder mounted on the face of the wheel for delivering the twine to the said twine wrapping tube, and a cutter for cutting the twine at a point between the said tube and the said support.

7. A machine for wrapping grafts, comprising a wheel mounted to turn, a twine holding spool journaled on the face of the said wheel, a twine wrapping tube provided at its inner end with a tached to the face of the wheel a distance from the center thereof, to hold the said twine wrapping tube parallel to the axis of the said wheel, the twine passing from the said spool to the inner end of the said twine wrapping tube and through the same, out of the forward end of the tube, a support for the in the said support, for

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
